We made several cardboard "Crystals" out of cereal boxes, tied them onto the dress and spray painted the whole thing silver for a UFO Alien Costume Co...
This dress and purse was made with plastic grocery bags.Ask your friends and family to save bags for you, it won't take long to get as many as you need! It took 40 bags to make the purse and about 200 for the dress. I made it for my daughter to model in the 2009 Santa Fe Recycle Art Trashion Show. We got 3rd place! The blue strips woven through the waist and the top edge of the purse was cut from a pretty blue plastic bag. I lined the dress with 3 old white cotton shirts from the thrift shop.
Flatten out the bag. cut off the bottom and the handles. Open up the bag and begin cutting a spiral strip about 1-1/2" wide, turning the bag as you go. Keep cutting until you have one long strip. Tie the ends of the strips together, cutting off the excess.Start rolling the strips into a ball. Continue tying strips together until you have 20 or 30 bags cut up. This can be time consuming but I like to cut the bags up while I'm watching TV and, before I know it, I've got a couple dozen bags cut up and rolled into a ball.
Step 2: Begin to crochet
You will need to use a large metal crochet hook, I use a size N/15. It might be a good idea to make a simple rug first, just to get the feel of the plastic. If you pull on the plastic too hard it will break, but once you get the hang of it, it goes pretty fast. This rug is being made with plastic bags from several different stores. I'm using a double crochet stitch, but I think a single crochet stitch would work also, it would just take more time.
